2 Claims. 1

This invention relates to sanding blocks designed for supportingsandpaper or emery paper in such a way as to facilitate the sanding ofsurfaces.

An important object of the invention is to provide a block which is soconstructed that the sandpaper or emery paper may be readily and easilyremoved therefrom and replaced.

Another important object of the invention is to provide a sanding blockwhich may be operated close to the edge of molding or surfaces extendedat right angles to the surface being sanded.

Still another object of the invention is to construct a sand block sothat it may be readily gripped by the operator, protecting flaps beingprovided to protect the fingers of the operator against contact with therough sand or emery paper used on the block.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claims, it being understood that changes may bebe made in the construction and arrangement of parts without departingfrom the spirit of the invention as claimed.

Referring to the drawing Figure 1 is a longitudinal sectional viewthrough a sanding block constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

' Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Referring to the drawing in detail, the sanding block comprises the bodyportion 5 which is formed with upstanding ribs 6 formed along thelongitudinal side edges thereof, the ribs 6 being formed with beveledsurfaces, as clearly shown by Figure 3 of the drawing.

Cooperating with the body portion 5, is the upper movable section 1which is of a width equal to the width of the body portion, and isprovided with depending ribs B, which ribs are spaced from the sideedges of the upper movable section, and are so shaped that they presentbeveled surfaces that cooperate with the inner beveled surfaces of theribs 6 in gripping the sanding paper which is indicated by the referencecharacter 9, therebetween. The reference character 10 indicates anelongated block which is disposed between the ribs' 6 of the bodyportion, the elongated block being of a length to extend through- 2 outth length of the body portion. This block is of a width so that spaces Hare provided between the side edges of the block and the inner surfacesof the ribs 6. The block it is secured to the body portion, by means ofthe screws l2.

An opening I3 is formed in the lower surface of the block II], at apoint intermediate the ends of the block, the opening being designed toaccommodate a nut It to which the threaded end of the screw [5 extends.This screw [5 also extends through the elongated opening IS, the screwalso passing through the block ll that rests on the upper movablesection l, directly over the opening it, as clearly shown by Figure 3 ofthe drawing.

By rotatin the screw I5 within the nut i l, it will be seen that theupper movable section I will be clamped between the block ii andelongated block I0.

Screws 2!] are also extended through the block, the pointed ends thereofcontacting the sand paper while the sand paper is being drawn tightlyaround the block, the pointed ends of the screws 25! cutting into thesand paper holding the paper taut while the sections of the block arbeing drawn together.

It will, of course, be understood that the sand paper which is stretchedover the block, is of a length so that it will pass between the ribs 6and 8 of the members 5 and i, so that the sand paper will be clamped inposition and held securely while it is being moved over the surfacebeing sanded.

As shown by Figure 3, the ends of the said paper extend to positionswhere they are overlapped on the upper surface of the block iii, thesand paper being formed with notches l8 providing a clearance for thescrew l5.

Secured to the extended longitudinal lower edges of the upper movablesection "5, are leather protecting strips 19 which overlie portions ofthe sand paper which would fall opposite to the fingers of the handgripping the sanding block while in operation. These strips of leatherl9 lie squarely against the sanding paper resting on the outer surfacesof the ribs 5.

From the foregoing, it will be seen that due to the construction shownand described, I have provided a sanding block which may be readilygripped by the operator and held in such a way that the sanding blockmay be' moved close to edges being sanded, and that the operatorsfingers and hands will be protected against abrasion by sand paper,while the sanding block is in op eration.

What is claimed is:

1. A sanding block comprising removably con! nected upper and lowersections between which an abrasive sheet is held, means for securing theabrasive sheet to the sanding block embodying, upwardly extended ribsformed along the longitudinal side edges of the lower section, the sidesurfaces of the ribs being beveled, ribs formed on the lower surface ofthe upper section, the side surfaces of the latter ribsbeing-beveled,the beveled surfaces of said sections cooperating in gripping theabrasive sheet therebetween, a rectangular block secured between theupper and lower sections, the ends of the abrasive sheet being alsoclamped between the block and upper section; and means for forcing theupper section into clamping relation with the block securing theabrasive sheet therebetween.

2. A sanding block comprising removably-connected upper and lowersections between which an abrasive sheet is held,'means for securing theabrasive sheet to the sanding block embodying, upwardly extended ribsformed along the longitudinal side edges of the lower section, the sidesurfaces of the ribs being beveled, ribs formed on the lower surface ofthe upper section, the side surfaces of the'l'atter ribs beingbevelecLthe REFERENCES CITED The following references are of record inthe file of this patent:
